why am i lvl 2 again?

Yea, that'll do it. Sometime 'new to bundle' stuff can be retroactively reduced from the start point.

I assume it's to prevent people from getting 'easy level 10s' from loading up on dollar bundles and giving them away later for full value.

when you added giveaways these games had full value, and now they have reduced:

• Turok 2: Seeds of Evil
• The Bard's Tale IV: Director's Cut
• Truberbrook / Trüberbrook
• ... and more I'm too lazy to check them all

For reference compare: this and this

It's retroactive only to the point of the start of the bundle (ignoring the rare instances where a staff member randomly adds a day or two to the start date, which may be a circumstance more open to discussion), which is a pretty darn necessary step for supporting the entire concept.

That is to say, you could argue you don't favor the bundle list in general, but if it fails to be retroactive then you get a sharp rift between those who intentionally exploit early and those who don't exploit, post later, and get worse benefits. Frankly, it'd probably be the worst possible arrangement they could have for the matter, as it'd actually emphasize the very exploitation the system is intended to curb.

While those new to the site do get caught in unexpected circumstnaces, after that initial confusion everyone either becomes familiar enough with the underlying concepts, or learns to simply to ask those who are, to get insight whether or not the game'll retroactively count as bundled in the future. Is it a bit of a bother? Sure, but no more than figuring out any random system you'd run into in a video game (in fact, this is more straightforward than most of those).

and you like 2 levels down holy shit. well gotta giveaway more games. level 4 at least is reasonable.

I know, I was being sarcastic. I edited my post while you were writing yours.
And he's done that with all the games that have achievements...

you can also play Games offline and when you go online, you might get all achivements at once (but it will be most likely sam)

From having another look, I think he has played some of the games. In the Steam privacy settings, there's an option that reads "Always keep my total playtime private even if users can see my game details." I guess he ticked it and that's why the playtime doesn't show.
Besides, it seems (for some games, at least) he unlocked some of the achievements the regular way and just used SAM for those he couldn't get.

Lol, they’re called achievements because you played the game and earned them. You just look like a douche if you didn’t actually unlock them by playing the game.
